I have been very happy with this purchase! I have used this light a number of times with students during Open Water and Advanced in a local quarry. It's very dark below about 30 feet and although I have a strobe on the back of my tank the students have difficulty seeing me beyond about 4 feet when I take them "on tour". I typically take the light and shine it over my right shoulder and students say it is a great beacon for them to follow.

Also, I've not had to change the batteries although I've logged at least 16 hours or more on the originals. The owner's manual suggested 4-6 hours of burn time, but I've far exceeded that and haven't noticed a reduction in power.

The grip is comfortable and shaped nicely to reduce fatigue and make one hand operation easy.

Great light for night dives. Strong, concentrated light beam. Turns on and stays on. A bit heavy and takes a bit of getting used to (particularly if you are petite) but thus far has been worth the investment. I have not had it long enough to assess bulb life or battery drain.

I am impressed with this light. I have only had this light for a couple of weeks and used it on 7 times. I have very big hands but it still handles fine, even with gloves. The beam is clear, bright and well defined. I am very impressed with the white LED light as well. It allows for much better visibility into holes and gives better definition of objects. The switch works really well. Its a least as good as any pistol lights I have owned, and that's quite a few. Use the lock off device when its not in use because it turns on easily.Interesting heat sink sticking out the front of the lens but it seems to do the trick.I really didn't see a big difference between high and low power setting. Low works the best for me anyway. I can't say about the battery life I still have the first set in use.Overall an excellent product so far.

I was really happy with this purchase as it was easily transportable overseas and was not too heavy. Previously had a halogen dive torch and this lamp was 10 times better. I recommend a caribina style retractor as it is light enough to hang to a D ring when not in use, too big too put in my BC pocket. Not a great deal of difference in the two light settings, however excellent for night dives.

Why Did You Choose This?

I was given this light as a gift from my wife and it ROCKED. I was leery about its large size, but during night dives with Blackbeards cruises, it really made a huge difference. I am buying one for my son to replace his puny dive light.
